Houkago Tea Time’s Bassist, Mio Akiyama, celebrated her birthday last January 15, and she is getting some new anime merchandise just to celebrate her birthday.

The character is a reason why many anime fans started playing the bass, and Japanese anime goods store, Animaru, has started offering a special light-up bass effector during her birthday. Called the K-ON! Mio Driver (K-MD1), this special birthday Bass effector costs 29,700 yen. When turned on, the effector’s bass engraving lights up. It also features a Houkago Tea Time control dial, so you can get similar settings to Mio herself.

Animaru is also offering up an acrylic glasses stand, featuring Mio’s face, so when you are not wearing your glasses, you can give Mio that good’ol Japanese megane look. The stand costs 3,700 yen.

A special Mio seal stamp, or itaindou, is also being offered for her birthday. Worth 4,860 yen, this Mio itaindou comes with a K-On! carrying case and an ink pad. It can be used to stamp official documents in Japan.
